I didn't for me, ended up taking my tire off and muffler from the tsudo instead of the brace under the gas tank, just slipped off the old sway bar without having to take off the muffler but after I got the new one in was a different story, Took off the muffler and then tried putting it back on and it was to tight on there, I would have to forced it into place and it would have been touching the sway bar and I already have had rattling from my exhaust hitting under the car, idk if anyone else with a tsudo exhaust has had that, I know one person has had that(the rattling)
